Wet Scrubber Not Working Properly?

Posted by Anthony DeLoach, President on Sep 12, 2022 8:47:33 AM

When it comes to Odor Control and Air Emission scrubbers, you're either pleased with how yours is working or highly frustrated with how it isn't.

While wet scrubbers are powerful devices that can reduce various harmful air pollutants and exhaust gases, not all are created equal. An operator's most common problem with a scrubber is a lack of performance. The following are some main reasons why your scrubber may not work correctly.

When it comes to designing a wet scrubber, different manufacturers have different design standards. Creating a device that can handle high throughput with reduced cleaning cycles. Others will develop a scrubber concentrating on the maximum removal of pollutants.

The wet scrubber that you purchase should be based on your specific needs. If you buy a scrubber not designed for your particular application, you're setting yourself up for problems.

Some factors will determine how well your scrubber will perform. Including the gas flow rate, gas pressure, the type of media used, and the design of the scrubber itself. If your wet scrubber design cannot handle your application's specific requirements, you'll experience reduced performance and increased downtime.

Faulty installation of the scrubber.

If your scrubber is not installed correctly, it will not perform properly. A poorly executed installation can cause a wide variety of issues.

The most common problem is channeling, which causes a low-pressure drop across the scrubber. The most common cause of this issue immediately after an installation is an out-of-level scrubber tower, followed by the improper placement of the media bed. A poor installation will cause reduced performance and allow odor or chemical breakthrough from the exhaust of the scrubber. The incorrect type of media in a scrubber can also cause a reduction in performance. Upon discovering a low-pressure drop, the scrubber should be inspected to ensure the installation was done properly and that the media bed is correctly sized and placed within the scrubber for its specific application. Remember, one size does not fit all regarding odor control and air emissions scrubbers!

First, make sure you hire a reputable engineering firm or work directly with a manufacturing company that has professional engineers on staff that have experience and specialize in wet scrubber design and installation. It's also essential to review the manufacturer's installation manual and follow the instructions.

How to Remove Nanoparticles from Your Drinking Water‍

Posted by Anthony DeLoach, President on Jul 22, 2022 1:14:33 PM

If you’ve been reading the news lately, you know nanoparticles are not so great. In everything from cosmetics to water filters, nanoparticles have been shown to cause various health problems. But what exactly are nanoparticles, and how can you protect yourself from their harmful effects? Let’s answer these questions and more with this quick guide on removing nanoparticles from your drinking water.

What are Nanoparticles?

Nano is a prefix that’s used to indicate how small something is. In the case of nanoparticles, it means particles less than 100 nanometers. Water filters that use nanoparticles are generally around 0.2 to 0.3 microns or 2,000 to 3,000 nanometers. That’s pretty small. There are some health concerns with nanoparticles. When ingested, they can cause inflammatory reactions in the body, disrupt normal organ function, and lead to a buildup of fluids in the lungs or other organs. A 2017 study found that the number of nanoparticles in drinking water is higher than expected and that using carbon filtration may make some nanoparticles more likely to leach into the water.

Where Are Nanoparticles Found?

Nanoparticles are found in a lot of modern products. Their small size makes them ideal for air and water filters, sunscreens, and cosmetics. It’s important to note that not all nanoparticles are harmful. Some are beneficial. Nanoparticles of silver are often added to water filters to help remove bacteria and other contaminants from drinking water. There are a few places where nanoparticles are most often found. - In water filters - Nanoparticles are often added to water filters to help remove bacteria and harmful contaminants. - In sunscreens - Some sunscreen products contain nanoparticles of zinc oxide, titanium dioxide, and other minerals that provide broad UV protection. - In cosmetics - Many makeups, lip balms, and other beauty products contain nanoparticles of iron, titanium dioxide, zinc oxide, and other minerals that help preserve the product and provide color.

Treating Noxious Fumes with an Odor Control Scrubber.

Posted by Anthony DeLoach, President on May 24, 2022 1:00:00 PM

A manufacturing facility cannot ignore the importance of odor control.

 

The smell from chemicals, vapors, and fumes can spread quickly in a small area. They cause discomfort to workers and pose health risks to them. In addition to that, excess vapors directly impact the efficiency of exhaust or natural ventilation systems. For example, an odor control scrubber tower is an additional layer in the ventilation system of a manufacturing plant or chemical processing facility that has issues with odors. These towers effectively remove noxious fumes and odors from ventilation exhaust streams using an activated carbon filter and an ionic air filter.

 

Reasons why you should consider installing an Odor Control Scrubber Tower :

 

Health & safety of workers.

 

Everyone working in an industrial environment, either directly or indirectly, is at risk of exposure to hazardous fumes and gases. At times, high concentrations of these gases may be emitted into the atmosphere in the form of unhealthy odors, putting the health and safety of the workers at risk. These gases may even be combustible in some cases, posing a significant threat to workers. The purpose of an odor control scrubber tower is to remove these gases from the contaminated air stream and help the workers stay safe. In addition, it reduces the risk of health issues such as nausea, headaches, loss of consciousness, allergy symptoms, dizziness, and many more. It also prevents workers from missing their daily performance targets due to sickness caused by toxic fumes.

 

Pro-environment step.

 

Although it is vital to protect the workers from exposure to harmful fumes, it is also essential to protect the environment. Odor control scrubbers are used in petrochemical refining, pharmaceutical, food & beverage, paper, mining, chemical, and pharmaceutical industries. Therefore, it is crucial to choose the right type of scrubber that suits your industry’s requirements. The right choice of equipment also protects the environment as it helps reduce operational costs and maintenance supervision. It also protects the environment because it produces minimal sludge and reduces the risk of corrosion.

PFAS in Drinking Water

Posted by Anthony DeLoach, President on May 4, 2022 1:05:00 PM

If you’ve been following the news, you know that there’s a growing problem with PFAS (per- and polyfluoroalkyl substances).

 

These man-made chemicals are found in everything from clothing to food packaging. While they are inexpensive and stable in products, some of these substances tend to break down into other substances, such as PFAS-methyl tetrahydrofuran. PFASs have been discovered in drinking water across the country, including in parts of the country with very high water tables. As a result, it’s important to learn how to remove contaminants from your drinking water. What should you do if you suspect that there’s a problem with your water? Check the source of the water, test it, and treat it if necessary.

Follow these steps to remove contaminants from your drinking water.

Test Your Water

Although it’s important to know how to remove contaminants in general, it’s even more important to know how to test your water for contamination. A water test kit can help you determine whether there are contaminants in your water and whether they are at a dangerous level. You can purchase water test kits at most grocery stores, hardware stores, and online retailers. Generally, these kits come with the standard set of tests for a home water filtration system, but they also often include tests for certain contaminants. Use these tests to determine whether your water is safe to drink or not. If your water contains contaminants, you need to remove them from your water source. This can be done by digging a deeper well, installing a water filtration system, or getting a water purification system. If your water does not contain contaminants, you don’t need to do anything except continue drinking your water.

What Is Water Turbidity?

Posted by Anthony DeLoach, President on Mar 18, 2022 1:05:00 PM

Water turbidity refers to how transparent or translucent the water is when examining or testing it for any given use.

Water turbidity can impact food and beverage, municipal, industrial, and aquaculture operations. Turbidity is caused by suspended or dissolved particles in the water that scatter light which causes the water to appear cloudy or even murky.

Different types of particles can cause turbidity, and they include sediments such as silts and clay, very fine inorganic or organic matter, algae or soluble colored organic compounds, and microscopic organisms. Turbidity is measured in a value referred to as NTU, which means Nephelometric Turbidity Unit. The EPA requires a turbidity level no higher than 0.3 NTU in the USA, and if a member of the partnership of safe drinking water, then the level must not exceed 0.1 NTU.

High turbidity can create habitats for other harmful elements, such as bacteria or metals, that can accumulate onto the particles. This increases the health risk for a potable water system. In aquaculture operations, increased turbidity from silts and sediments can be harmful and detrimental to marine life, so it must be removed to safe levels. For the food and beverage industry, the impact of high turbidity can be both a safety concern and a visual and noticeable quality concern because if the turbidity is high, it can alter the physical look of the final product, for example, a distillery.

How to Remove PFA'S from your Water

Posted by Anthony DeLoach, President on Feb 22, 2022 1:02:58 PM

The EPA and other world health organizations have recognized the dangers and health impacts of being exposed to PFASs.

Federal and State regulators are adopting new guidelines and laws for treating and removing PFASs. Often PFASs within potable drinking water systems or groundwater is contaminated with one of the various types of PFASs. There are over 4700 different variations of PFASs that have variations and at least three polyfluorinated carbon atoms.

Well over 10,000 types of PFASs are introduced into products. That can and has impacted the drinking water quality in the USA and other countries. 

So what are PFASs?

PFASs are fluorinated substances that include at least one fully fluorinated methyl or methylene carbon atom. They do not contain (H/Cl/Br/I atoms). However, any chemical with at least a perfluorinated (CF3) or a perfluorinated (CF2) is a PFAS. There are a few exceptions.

Different subgroups include surfactants, per fluorosulfonic acids, perfluorooctane sulfonic, perfluoro carboxylic, and perfluorooctanoic acids. Often referred to as PFOSs and PFOAs.

PFOS, PFOA, and other PFASs are persistent organic pollutants. They are often referred to as the "forever chemicals" because they do not easily break down in the environment. These organic contaminants are found in humans, animals, and our water supplies across the USA.

What is Water Demineralization?

Posted by Anthony DeLoach, President on Jan 27, 2022 12:54:16 PM

Water demineralization is also called deionization and is a process known as “Ion Exchange.”

In simple terms, water demineralization is “Water Purification.” The process involves removing dissolved ionic mineral solids from a feed-water process, typically for “Industrial” water applications. Still, it can also be utilized to remove dissolved solids from a water process for “Aquaculture,” “Food and Beverage,” and the “Municipal” markets.

Why is demineralization utilized? It can remove dissolved solids to near distilled water quality at a much lower capital and operational cost than other treatment processes such as membrane softening (Reverse Osmosis). Demineralization applies the science known as “Ion Exchange,” which attracts negative and positive charged ions and allows either to attach themselves to a negative ion depending on their respective current negative or positive charge during what is known as a resin cycle. In other technical articles, we will explore and go into more specific details on the science of the ion exchange process. Water that has dissolved salts and minerals has ions, either negatively charged ions known as “Anions” or positively charged ions known as “Cations.” To treat the water and remove these contaminants, the ions in the water are attracted to counter-ions, which have a negative charge. In a demineralization treatment process, there are pressure vessels that hold resin beads which are typically made of plastic. The beads are made from a plastic material with an ionic functional group that allows them to hold and maintain an electrostatic electrical charge. Some of these resin groups are negatively charged, referred to as “Anion” resins, while others hold a positive charge and are called “Cations” resins.

There are different applications to apply Ion exchange technologies, which is why you will often hear the different terminology interchanged like deionization and demineralization. The raw water quality and the specific application will dictate the type of ion exchange process needed. For example, if the water contains a high level of hardness, the water will most likely contain Ca2+ or Mg2+ dissolved solids possessing a positive charge. To replace these hard ions, it is typical to utilize a resin bed with a salt ion like Na+. As the water passes over the resin bead material within the pressure vessel. The hard ions are replaced with the salt ion; therefore, all the hardness within the water is removed. However, the water will now contain a higher concentration of sodium ions, and this must be considered during the evaluation and selection process of the type of resin material to utilize for the specific application. If the water application requires high purity and the removal of as many solids as possible, then the term or process selected is referred to as demineralization.

Benefits of Pressure Filters for Industrial Water

Posted by Anthony DeLoach, President on Jan 4, 2022 1:00:00 PM

Industrial water systems use water filters to reduce the level of solids in water from:

  • Industrial
  • semiconductor
  • manufacturing
  • refining
  • oil and natural gas production processes

The wastewater may contain harmful chemicals to humans, plants, or animals. Three types of filters are commonly used in industrial settings: Gravity filters, pressure filters, and constructed wetlands. Pressure filters have two variations: multimedia and higher-pressure micron or cartridge filters. Constructed wetlands or natural filters are not often utilized in industrial processes. Based on the requirements to obtain environmental permits and safeguard the ecosystem.

Technology to Remove Per- & Polyfluorinated Substances

Posted by Anthony DeLoach, President on Dec 14, 2021 1:00:00 PM

Per-and polyfluorinated substances (PFAS) have been used for decades in many consumer products, and they are man-made and have a high residual time in the environment. These chemicals are used for various purposes, including nonstick surfaces, heat protection of circuits, water resistance, fighting fire as they are utilized in fire depression foam, and many other industrial applications. The difficult thing about PFAS is that the very reason they work so well on so many manufactured products is why they are so challenging to get rid of or treat once they have entered the environment or water supply. PFAS are being more and more regulated, and requirements are being put in place by many states and agencies to require the treatment and removal of PFAS and safeguard and protect drinking water.

PFAS are soluble in water, and they are not a volatile organic chemical (VOC), so traditional treatment methods such as utilizing an air stripping tower or degasification system are not effective methods to remove PFAS. One of the first technologies to remove PFAS from drinking water and the environment is activated carbon absorption. In recent years, utilizing ion exchange resins has proven effective and is gaining popularity for the treatment method. Ion exchange resins attach and bond with the PFAS and remove it effectively from the water. Some chemicals tested and studied with success include perfluorooctanoic acid (PFOS). In addition to these technologies, reverse osmosis utilizing high-pressure membranes has an 80-90% effective rate and has proven to be technically efficient in removing PFAS. An R.O. process produces a concentrated waste stream.

Using Aeration To Remove Iron from Water!

Posted by Anthony DeLoach, President on Oct 22, 2021 1:00:00 PM

Converting Ferrous (Fe+2) (soluble) iron to Ferric (Fe+3) (Particulate/Solid form).

The iron must first be exposed to air or another form of an oxidizing agent. Aeration is the most cost-effective method to oxidize ferrous iron for its removal from water. In many areas around the globe, municipal and industrial operations have the need to remove naturally occurring iron (Fe) from the water to both prevent damage to other equipment as well as to improve water quality. To remove iron from the water it first must be oxidized using the most widely accepted and cost-effective method called aeration. The aeration process changes the iron from its Ferrous (Fe+2) state (soluble) to ferric (Fe+3) a colloidal participate. Did you know that Iron occurs naturally and is found in the earth’s crust? It occurs in both groundwater as well as surface waters and is not known to cause any harmful effects on humans or animals.

Iron does cause problems though for municipal facilities and their customers by impacting laundry operations, causing stains on buildings, on plumbing fixtures. Iron also promotes and facilitates the growth of iron bacteria in water that creates a problem for distribution lines and piping systems. Once the lines become blocked this impacts the ability to distribute water to the customer. The presence of iron bacteria also becomes detectible even at low concentrations and impacts the taste of the water. The U.S Public Health Service Drinking Water Standard set a recommend maximum level of 0.3 mg/L in public water supplies.
